摘要: An apparatus for electroplating a layer of metal onto a work piece surface includes a membrane separating the chamber of the apparatus into a catholyte chamber and an anolyte chamber. In the catholyte chamber is a catholyte manifold region that includes a catholyte manifold and at least one flow distribution tube. The catholyte manifold and at least one flow distribution tube serve to mix and direct catholyte flow in the catholyte chamber. The provided configuration effectively reduces failure and improves the operational ranges of the apparatus.

摘要: Methods, apparatuses, and various apparatus components, such as base plates, lipseals, and contact ring assemblies are provided for reducing contamination of the contact area in the apparatuses. Contamination may happen during removal of semiconductor wafers from apparatuses after the electroplating process. In certain embodiments, a base plate with a hydrophobic coating, such as polyamide-imide (PAI) and sometimes polytetrafluoroethylene (PTFE), are used. Further, contact tips of the contact ring assembly may be positioned further away from the sealing lip of the lipseal. In certain embodiments, a portion of the contact ring assembly and/or the lipseal also include hydrophobic coatings.

摘要: Disclosed herein are cups for engaging wafers during electroplating in clamshell assemblies and supplying electrical current to the wafers during electroplating. The cup can comprise an elastomeric seal disposed on the cup and configured to engage the wafer during electroplating, where upon engagement the elastomeric seal substantially excludes plating solution from a peripheral region of the wafer, and where the elastomeric seal and the cup are annular in shape, and comprise one or more contact elements for supplying electrical current to the wafer during electroplating, the one or more contact elements attached to and extending inwardly towards a center of the cup from a metal strip disposed over the elastomeric seal. A notch area of the cup can have a protrusion or an insulated portion on a portion of a bottom surface of the cup where the notch area is aligned with a notch in the wafer.
